GSM based remote monitoring

Abstract

Critical nature of certain processes has made 24 hour daily monitoring and remote signaling an essential requirement despite the practical difficulty in fulfilling it. On the other hand the advancement of technology has opened new ways to communicate between man and machine by generating Human Readable text instead of Indicator bulbs and Audible alarms which are also stationary. Since SMS utilizes the unused component of the GSM voice bandwidth almost every GSM mobile service provider lets subscribers send and receive SMS for a nominal fee. Thus, SMS opens a new media for cost effective communication, across the globe to a fraction of the cost usually incurred in making a Voice call. The aim of this project is to provide Proof of Concept to an effective way to communicate the occurrence of an event to a geographically remote location in a cost effective manner. The functionality is explained by simulating the Input of a Burglar Alarm which causes a Status change of the monitoring system, which in-turn triggers sending of an SMS to a predefined number describing the condition.
